Engineering Services

The 45,700 engineering services firms in the US provide evaluation, investigation, planning, design, and development services related to utilities, structures, buildings, machines, equipment, processes, or systems. Specialty areas include civil, mechanical, industrial, electrical, electronics, computer hardware, aerospace, environmental, chemical, health and safety, materials, petroleum, nuclear, and biomedical engineering. Firms work on specific projects for clients and must be adept at project planning and management.

Dependence on Highly Skilled Personnel

Engineering service firms rely on a highly-educated, professional workforce.

Liability

Work site hazards and the complexity and scale of engineering projects expose engineering services firms to liability.

Sep 23, 2026 - Engineering Firms Maintain Strong Backlogs

• Engineering firms remain financially confident despite a more cautious economic outlook, according to the ACEC Research Institute's third-quarter business sentiment study of 591 engineering executives. Strong backlogs and hiring demand can give engineering services firms greater visibility into workloads while increasing pressure to recruit and retain skilled workers. Nearly half of respondents reported at least one year of backlog, and the median backlog remained at 12 months. Some 88% of firms had at least one open position, and 65% expected hiring to increase during the next 12 months. Sentiment was strongest in data centers and water and wastewater work, although respondents expressed growing concerns about inflation and broader economic uncertainty.
• Engineering News-Record reports infrastructure, power, and land development projects are supporting growth among design firms across Texas and the Southeast. Continued strength in transportation, water and wastewater, aviation, and power work can support engineering project pipelines, while firms may need additional expertise in utility planning, permitting, and complex infrastructure coordination. Data center development also is making land and power capacity more competitive, increasing demand for early site evaluation and infrastructure planning. Firms cited tariffs, interest rates, workforce availability, and AI integration as challenges. Despite those headwinds, design firms expect water and wastewater infrastructure, power delivery, aviation, and urban development to remain among the region's strongest near-term growth areas.
• The US Energy Information Administration expects electricity generation to rise 2.2% in 2026 to a record 4,368 billion kilowatt-hours, followed by another 1.7% increase in 2027. Rising power demand can create engineering opportunities involving generation, transmission, distribution, grid resilience, site infrastructure, and other electrical systems. EIA says data center development and increased manufacturing activity are driving commercial and industrial demand, particularly in the West South Central region. Electricity sales are projected to increase almost 2% this year and another 2% in 2027. Natural gas is expected to supply 40% of generation in 2026, while solar's share increases to 8%, adding to the variety of generation and infrastructure projects requiring engineering expertise.
• According to FMI's third-quarter 2026 North American Engineering and Construction Outlook, US construction spending on nonbuilding structures is forecast to grow 2% in 2026. Conservation and development spending is expected to lead growth at 13%, supported by the US Army Corps of Engineers' $10.4 billion fiscal 2026 civil works appropriation. Power spending is projected to rise 2% as data center demand drives utility investment, although equipment and connection constraints limit near-term growth. Highway and street spending is forecast to increase 2%, supported by committed Infrastructure Investment and Jobs Act funding. Sewage and waste disposal spending is expected to rise 2%, while water supply spending increases 1%, with data centers and advanced manufacturing supporting long-term water demand. Total nonbuilding structures spending is forecast to increase 5% in 2027, 9% in 2028, 9% in 2029, and 8% in 2030.
